The web services infrastructure

CICS® applications in a CICS region can either provide a service to, or request a service from, applications that are external to that region by using a web services pipeline. When CICS is a service provider, the CICS application supplies a service to the external application. When CICS is a service requester, the external application supplies a service to the CICS application. Web services pipelines can be configured to use zEnterprise® Application Assist Processor (zAAP) where available.
